VC6下不认识LPFN_CONNECTEX怎么办？

[chengwei02]

听说要使用什么SDK，是这样吗？
怎么解决？

先定义一个LPFN_CONNECTEX指针，然后通过WSAIoctl获得函数地址。参考：

LPFN_CONNECTEX lpfnConnectEx = NULL; // a pointer to the 'ConnectEx() ' function
GUID GuidConnectEx = WSAID_CONNECTEX; // The Guid

Once the socket is created, we have to bind it to a port and interface. While using 'ConnectEx() ', binding has to be done explicitly because the main purpose of this API other than allowing overlapped calls is, performance.

dwErr = WSAIoctl(cliSock,
SIO_GET_EXTENSION_FUNCTION_POINTER,
&GuidConnectEx,
sizeof(GuidConnectEx),
&lpfnConnectEx,
sizeof(lpfnConnectEx),
&dwBytes,
NULL,
NULL);
if(dwErr == SOCKET_ERROR)
// Handle the error using 'WSAGetLastError() '

这是啥东西?
我这VS2008的MSDN也没找到这个

[chengwei02]

关键是LPFN_CONNECTEX不认识

[猫已经找不回了]

帮up

为啥这么严重？

在mswsock.h中？那你安装sdk没有？

[UndefinedCoder]

MSDN里查ConnectEx就有了。

嗯，要SDK的头文件。

[chengwei02]

no one knows?
